Next, the operation will be explained.

The cold air cooled by the cooler (7) is blown into the freezer compartment (7) from the freezer compartment outlet (8) by the fan (3) driven by the motor (4), and is then blown out into the freezer compartment (7) from the bottom surface of the freezer compartment (1). A part of the cold air is taken into the ice-making corner (111), which passes around the ice-making tray (6), passes through the freezer compartment suction port AS, and returns to the cooler (5)K.

[Problem to be solved by the invention]

Since the ice tray or ice container used in conventional refrigerator-freezers is constructed as described above, it is free from impurities such as residual chlorine and hardness, which are the source of chlorine odor, just like tap water in ordinary homes. When water containing water is frozen in an ice cube tray, the impurities are removed as it freezes.

There is a problem that the ice transfers to the unfrozen state and becomes concentrated in the final frozen part, resulting in a cloudy part, and depending on the water quality, unpalatable ice with many cloudy parts is made. In order to solve these problems, a double-structured ice making container Mfi3 consisting of an upper ice tray I and a lower ice tray I as described above has been developed, but the upper ice tray,
Since the bottom part (A) of the ice block formation chamber member of the ice block formation chamber 0 is formed in a flat shape, the water mixed with impurities does not concentrate in the space αη below the communication hole of the ice block formation chamber 0, and the ice block formation chamber 0 does not concentrate. Formation chamber a
At the bottom of No. 9 (a), K is deposited, resulting in cloudy water, and the above-mentioned problems have not been improved as much as before.

Furthermore, the ice that has frozen from water that has flowed around the gaps around each ice cube on the upper ice tray connects with the ice cubes in the lower ice tray, requiring considerable force to separate the upper ice tray and the lower ice tray. In addition, it is very difficult to remove ice because it inhibits the deformation of the ice tray, and the problem is that the ice that has not been sufficiently separated from impurities gets mixed with the ice cubes in the ice tray during ice removal. There was also.

Also, even if the ice making container has a double structure as shown in Figure 19, the first
When making ice using a conventional refrigerator-freezer as shown in Figure 6, the ice making container is cooled from all around by circulating cold air. The inside of the ice tray also begins to freeze.Therefore, there is a problem in that the final frozen portion containing impurities is located near the bottom of the ice tray.

This invention was made in order to solve the above-mentioned problems, and it provides an ice-making container that can produce clear ice without cloudy areas where impurities are concentrated even when freezing water of poor quality. It is an object of the present invention to provide a freezing chamber for ice making in which the double-structured ice making container can fully exhibit the ability to separate impurities during ice making.

[Means to solve the problem]

The ice-making container of the present invention includes an ice-making block having a first inner wall surrounding the ice-making block and a bottom surface, and an impurity block having a second inner wall surrounding the ice-making block and a bottom surface, and includes an upper ice-making block and the impurity block. The block is removable,
A space is provided between the bottom surface of the ice making block and the bottom surface of the impurity block, and a space above the bottom surface of the ice making block and a space below the bottom surface of the ice making block are connected to a part of the bottom surface of the ice making block. Provide a communication section for communication, and.

The ice making block or the impurity block may be provided with an outer wall covering at least three sides of the ice making container. Moreover, the ice-making freezer compartment of this invention is as follows.

The bottom surface K of the freezer compartment instead of the outer wall of the above ice making container.

A recess with walls covering at least three sides of the ice-making container is provided, and a heating source is provided.

[Effect]

In the ice-making container of the present invention, since the communication part that communicates with the impurity block side is formed on the bottom of the ice-making block, when water containing impurities is injected into the ice block formation chamber of the ice-making block, the water contains This is because the impurities contained in water have a higher specific gravity than pure water.

The cloudy part, which is concentrated with impurities, can be guided downward to the lower ice making tray through the communication hole by the slope of the bottom part, and transparent ice can be formed in the ice block forming chamber. Furthermore, the ice-making container of the present invention has an outer wall that covers at least three sides of the ice-making container composed of two communicating layers.
By providing a recess with a wall covering both sides or a heating source, it is possible to ensure that the ice in the ice making container freezes from the top and freezes on the bottom side last, removing impurities and making pure water Make clear ice reliably.

〔Example〕

This invention will be explained below with reference to the drawings.

1 to 3 are diagrams showing a refrigerator-freezer equipped with an embodiment of the ice-making freezer according to the present invention, and FIGS. 1 and 2 are front views of the refrigerator-freezer excluding the door, and FIG. is a sectional view.

Note that the codes (1) to (111) indicating the refrigerator-freezer are the 10th
Since it is the same as the figure, it is omitted.

In the figure, c211 is the refrigerator compartment, @ is the vegetable compartment for storing vegetables, which is provided below the refrigerator compartment Qn, and (c) is the refrigerator compartment 2.
An ice-making compartment installed to divide the space between 11 and the freezer compartment (1). 4 is the ice making room (to) and the ice greenhouse installed side by side, (to) is the ice making room installed side by side, (to) is the ice greenhouse (
The upper partition provided between the upper part of the freezer compartment (1) and the freezer compartment (1), @
is the lower partition installed between the lower part of the ice making room (to) and the ice greenhouse (Foundation) and the cold storage room an. This is a vertical partition in between.

(To) is a rapid ice-making tray, which is a conventional ice-making container located at the top of the ice-making compartment (To), and (To) is an ice-making container with a partition provided at the bottom of the tray through a fence.

Furthermore, as shown in FIG. 2, an ice storage container may be provided instead of the partition wall. (To) is the ice-making compartment air outlet located on the back of the rapid ice-making tray (To), and (To) is the ice-making compartment suction port located at the back of the ice-making container (To).

Further, (to) is a cold air air path provided between the lower surface of the partition wall @ or the water storage container on and the upper surface of the ice making container M (to). (To) Ice maker outlet (To) K Guides cold air (Duct (To)
2) is an air guide that constitutes.

[Yes] is a recess that is provided on the bottom of the freezer compartment (1) and has walls that cover at least three sides of the ice-making container (to) installed inside, and the sides and sides of the ice-making container (to) installed inside. Since the flow of cold air is obstructed by the recessed basket at the bottom, the ice making container (to) is cooled from the top by the cold air flowing through the cold air passage (to).

Next, the ice making process of this refrigerator-freezer will be explained. First, a part of the cold air cooled by the cooling M (5) is transferred to the freezer compartment air outlet (
8) and cools the freezer compartment (1). In addition, some of the cold air is passed through the duct (b) between the fan grill (7) and the air guide (to) to the ice-making compartment outlet (to).

Cold air is blown into the ice-making compartment and cools the rapid ice-making tray located at the top of the ice-making compartment. Road (
Cold air is circulated through the ice-making compartment suction port (to) and back to the cooler (5)K. By circulating the cold air in this manner, the cold air from the outlet of the quick ice making tray (hereinafter referred to as "to") flows around the quick ice making tray including the side and bottom surfaces, thereby cooling the entire body and shortening the time. On the other hand, the ice container (to) is in the freezer (
1) is housed in a recess (b) whose left and right sides are covered with walls, so cold air does not flow around the ice-making container (to), and the bottom surface contains the lower ice-making tray (AD and soft The ice making container ω is insulated by the air layer created by the container, so the ice making container ω has a cold air path (
(To) The cold air flowing inside gradually cools down from the top and freezes.

The ice making container used here can produce ice free of impurities even if the conventional ice making container Q'3 shown in FIG. 1B and FIG. It is possible to reliably make ice that does not contain any impurities.

In the above embodiment, an example was explained in which a quick ice making tray and an ice making container were arranged vertically in the ice making compartment of a 5-temperature type freezer/refrigerator, but the ice making freezer compartment of the present invention can be used as long as it is a space or air path where freezing can occur. It is possible to separate transparent ice from cloudy ice with any spatial air channel structure.

In addition, since the water freezes from the upper surface, the ice making container α2 may be formed of a flexible material such as polyethylene in order to absorb the volumetric expansion caused by freezing of water.

The structure of an embodiment of the ice-making container of the present invention is shown in FIGS.
This will be explained using FIG.

(29a) is an ice-making block in which the opening edges of a plurality of independent blocks having a first inner wall surrounding the surrounding area and a bottom (29a) are continuous, and the bottom (29a) of each ice-making block (29a)
It has a communication part consisting of a plurality of holes. I is an impurity block that covers the outer periphery of the ice making block other than the upper opening and is removable from the ice making block. The first inner wall (c) and the second
It has a double wall structure with an inner wall 07>. Then, the bottom (to) of the ice making block (to) and the impurity block (to)
A lower space 04 for forming ice made of concentrated impurities is formed between D and the bottom surface.

Above the bottom of the ice-making block (to) is an upper space IA1 and an upper space i4 for making ice from which impurities have been removed.
3 is formed.

Further, an outer peripheral wall (51) is provided around the second inner wall, and the upper part of this outer peripheral wall (51) is the impurity block C.
an outer wall (52) connected to D, and an outer bottom wall (52) connected to the outer wall (52) and covering the bottom surface of the impurity block CD;
5).

In the impurity block CD, the height of the first inner wall (c) is made higher than the water level (to) of the ice making block (to).

The cloudy white ice mixed with impurities formed in the lower space I on the lower side facilitates the separation of a plurality of independent pieces of ice. The water in the ice making container is cooled from the sides and bottom, and is prevented from freezing from the sides and especially from the bottom. In other words, after the freezing in the ice making block (to) is completed, the impurity block IAa is set so that the freezing in the impurity block (to) is completed.
On the outside of the second inner wall IAn and the bottom surface (1), there is a second inner basket IAη, the bottom surface (sha), the outer wall (52), and the outer bottom wall (55).
A closed space layer nl with a low heat transfer rate surrounded by is provided.

It is best to cover the impurity block (4D) with a layer with a low heat transfer rate such as the closed space layer Oη.

The part of the ice that contains the most concentrated impurities is the ice container (
The ice containing the most concentrated impurities is located above the bottom of the ice making block (2), and the ice containing the concentrated impurities is placed above the bottom of the ice making block (2). This eliminates the worry of not being able to separate the ice that is missing.

This closed space layer (4!I may be simply an air layer.

Alternatively, it may be filled with a liquid or gas having a low heat transfer rate.

This impurity block (40 is preferably made of a soft material so that the impurity block (AD) can be more easily separated from the ice making block @).

First, when water is poured from the top opening of the ice making container (to) of this invention, that is, the top surface of the ice making block (to), the water flows into the upper space [3].
and accumulates in the lower space.

Here, the first inner wall of the ice making block (1) and the second inner wall of the impurity block (41) are in surface contact.

Since it is watertight, the lower space (441 water is
This prevents it from being enclosed in the outer periphery of the inner wall (to), and after freezing, the ice block in the lower space (44 is connected only to the ice block in the upper space US and the communicating part +4[1, so The ice making block (to) and the impurity block (to) can be separated with a slight force, and since there is likely to be an ice block between each first inner wall (c) that prevents deformation, the ice making block (to) must be twisted. Because it can be easily transformed into ice-making blocks (to)
Ice blocks in the upper space vessel can be easily removed, and there is no need to worry about leaving ice blocks containing impurities during the ice removal process.

and,#! The first mrl of the ice diblock (t)

2 spaces 143° C4 are formed above and below via a communication section 14tl consisting of a plurality of holes provided in the bottom surface (to) of the independent ice-making block (to), and cooling is gradually carried out from the open top surface. Therefore, the space of the ice making block (to) 6j
Maybe freezing begins and finally the impurity block (40 space G
Number 4 freezes. When ordinary household tap water is used, impurities such as residual chlorine or hardness migrate to the unfrozen portion during ice making and are concentrated in the final frozen portion, resulting in cloudy water. Therefore, the part that freezes first becomes clear, delicious ice that contains no impurities and is close to pure water. Therefore, transparent ice is generated in the space IAj of the ice making block (to), and the space of the impurity block Oυ! 44, cloudy ice is generated.

The @ wall height (to) of the impurity block GIO is higher than the water level of the ice making block (to). Just like a heavy-duty ice tray, you can deform the ice tray and release ice by applying force to both ends of the ice tray and twisting the upper ice tray and the lower ice tray at the same time.

Further, since the upper space (43) and the lower space 04 are connected only through the communication portion (41), the ice in the upper space after freezing and the ice in the upper space G141 are separated at the same time.

FIG. 8 shows an optical embodiment in which a layer (57) with a lower heat transfer rate is provided below the closed space layer shown in FIG. This can be prevented even more reliably.

Even if it is not necessarily a separate body, the outer bottom wall (53) may be made thicker.

@Figure 9 shows the bottom surface (4) of the second inner wall (47) on the impurity block (to) side that constitutes the sealed space layer shown in Figure 4, and the outer wall (52) on the outer peripheral wall (51) side. The outer bottom wall is constructed separately.

The impurity block having a closed space layer (4!) shown in Fig. 4 requires at least two manufacturing steps, but the one shown in Fig. 9 has the advantage that it can be manufactured in one process. have.

By the way, the communication device does not have to be a circular hole like in the above embodiment, but can be any shape of hole as long as each hole is small. For example, it can be a narrow slit. .

When this communication section has a plurality of holes or slits all over the bottom surface (2) of the ice-making block (2), it is easier for impurities to migrate from the upper space (2) to the lower space (2) during freezing.

By the way, one embodiment of the ice making container of the present invention shown in FIGS. 4 to 9 has a space layer that covers the impurity block itself, but the sealed air layer of the ice making container shown in FIGS. 4 to 1 In order to manufacture an impurity block having the following properties, two steps are required: separately making the second inner@wall side and the outer peripheral wall side, and then bonding both. Further, the ice making container shown in FIG. 8 requires a step of pasting an additional layer (57), and the ice making container shown in FIG. 9 requires three parts, although the number of steps is not increased.

Next, an embodiment of the ice making container of the present invention, which requires no preparation process and has a small number of parts, will be described with reference to FIGS. 10 to 12.

In the figure, the same or corresponding parts as in FIGS. 4 to 6 are designated by the same reference numerals, and therefore their explanation will be omitted.

The difference between the ice making containers shown in FIGS. 10 to 12 and the ice making containers shown in FIGS. 4 to 6 is that there is no outer bottom wall.

An opening (56) for a handle is provided on the outer wall (55) where the front door aK of the freezer compartment is located when installed inside the freezer compartment.

The ice making container (54) of this embodiment is covered by the outer wall (55) on both left and right sides and on three sides, so the outer wall (55)
It is difficult for cold air to pass through the space (57) located around the second inner wall of the impurity block KO on the inside of the ice making container.
), and the impurity block freezes last, making it possible to reliably create ice cubes that do not contain impurities.

In the ice making container with the above-mentioned sealed space layer, there is still a large difference in the way the ice making block (to) side is cooled and the way the impurity block-D is cooled, but this ice making container has a handle opening ( 56), it is extremely easy to take it in and out of the freezer compartment, and only requires two parts: the ice-making block (to) and the impurity block (+1).
No process is required.

Moreover, since the ice-making block (to) can be changed by twisting, etc., the space inside the ice-making block (to) (43) can be easily removed from ice cubes, and the impurity block (to) can also be deformed by twisting etc. Since this is possible, ice blocks in the space (b) in impurity block al can be easily removed, and the ice block in impurity block I can be used for cooling without eating up the ice blocks. It has new effects.

As shown in FIG. 11 and FIG.
It is sufficient if it is close to 3.

Further, the outer walls (55) of this ice-making container may be provided on at least three sides as shown in FIGS. 11 and 12.

Furthermore, the outer wall (55) of this ice-making container is formed integrally with the impurity block I, but even if it is formed integrally with the ice-making block @ side, it will have exactly the same effect.

All of the above-mentioned inventions delay cooling in three directions: upward and downward, but one embodiment of the invention delays freezing in the lower part than freezing in the upper part by actively supplying heat to the secondary part. An example will be explained using FIGS. 13 to 15.

In the figures, the same or equivalent parts as in FIGS. 1 to 3 are denoted by the same reference numerals, and their explanations will be omitted.

In the figure, (58), (59), and (tsO) are heat insulating walls that cover both sides and the bottom of the recess. (61) is a heater as a heat source provided with a heat insulating wall (b) K which is a bottom wall close to the bottom of the ice making container a3. Ice container (
(to) is a conventional ice-making container shown in FIGS. 18 and 19.

The ice making containers shown in FIGS. 4 to 12 described above may also be used.

Next, the operation will be explained.

A part of the cold air cooled by the cooler (5) is sent to the freezer compartment 1υ
It is blown out from the freezer compartment air outlet (8) made in the fan grill 17) on the back of the refrigerator, and cools the freezer compartment (1). Also, some of the cold air is transferred to the fan grill (7) and air guide (to).
The air is blown out from the ice-making compartment air outlet (to) to the ice-making compartment via the duct (b) between the ice-making compartments, and cools the rapid ice-making tray (to) located at the top of the ice-making compartment, and the returned cold air is passes through the cold air passage between the partition plate or the bottom surface of the water storage container Ql and the top surface of the ice making container (to), and from the ice making compartment suction port (to).

Cooler (5) k Return cold air is circulated.

Kl like this! ! By configuring the air passage of the ice compartment (2), ice making time is shortened because low temperature cold air is directly cooled to the rapid ice making tray @ at a high wind speed. - On the other hand, the ice making container (to) has relatively heated return cold air passing through the top, and the bottom and left and right sides are insulated walls (58) (59) (do).
Since the inside of the recess (b) is covered on both sides and the bottom, the ice cube will freeze gradually and slowly starting from the top of the ice making container (top). Furthermore, by intermittently heating the bottom surface for a certain period of time using the heating heater (61), it is possible to ensure that the bottom surface is gradually frozen from the top surface.

The ice making container (to) exposed to the cold air is reliably frozen from the upper surface of the upper ice making block, and the impurity block is frozen after the heater (61) is stopped. In other words, when the ice-making block freezes, impurities such as residual chlorine or hardness, which are the cause of the chlorine odor in tap water in ordinary homes, migrate to the space inside the impure block where unfrozen water accumulates and become concentrated. ) The space in the impurity block heated by KJI is the last to freeze.In this way, impurities are deposited in the space in the impurity block that freezes after KJI, and are trapped in the ice, creating a cloudy part, and the part that freezes first is , resulting in delicious ice that is almost as clear as pure water ice that contains almost no of these impurities.

Make sure that the ice container does not deform slightly and the ice does not bulge up due to pressure.
are doing.

In the above example, the ice-making tray and ice-making container were arranged vertically in the ice-making compartment of a five-door refrigerator-freezer, but as long as there is a heating source near the bottom of the ice-making container, transparent ice can be made with any air passage structure. It is possible to separate the cloudy water, and the heat insulation Qi (5B) (59) to prevent cold air from hitting the sides of the Kg ice container as in the above embodiment is not necessarily required.

〔Effect of the invention〕

In the ice-making container of the present invention, a communication portion communicating with the impurity block side is formed at the bottom of the ice-making block, so that in case water containing impurities is injected into the ice cube forming chamber of the ice-making block, the This is because the impurities contained in water have a higher specific gravity compared to pure water.

The cloudy part, which is concentrated with impurities, can be guided downward to the lower ice making tray through the communication hole by the slope of the bottom part, and transparent ice can be formed in the ice block forming chamber.

Furthermore, the ice making container of the present invention has an outer wall that covers at least three sides of the ice making container which is composed of two communicating layers.

Furthermore, since the ice-making freezer compartment of the present invention is provided with a recess or a heating source having walls covering at least three sides of the ice-making container consisting of two communicating layers on its bottom wall, freezing inside the ice-making container is ensured. It is possible to freeze from the top surface and freeze from the bottom surface side, which has the effect of making it possible to reliably produce transparent ice made of pure water free of impurities.
